The depth of tree roots depends on the species. Trees like oaks and maples can have root systems that grow down 20 feet or more. However, trees that grow in shallow soils will have roots that go only a few feet down. Research how your tree species grows in your climate area to estimate root depth.

Hiring an arborist or tree surgeon is usually more expensive than a standard tree company, but it is often worth the investment. Arborists have education and certifications that standard companies typically lack, leading to a more professional, expert-level service. Their expertise is particularly valuable for diseased or infested trees, as they can ensure safer removal and help prevent the issue from spreading. Additionally, arborists may be necessary for work near power lines, as uncertified companies are often not permitted to service these trees. If your goal is to preserve the health of your trees, an arborist is the best choice. Their services, such as stump grinding, are also performed with greater expertise to ensure a safe depth that won't cause your lawn to collapse over time.

Only trim palm trees as needed, which is usually about once per year. However, don't stick to that schedule if the palm tree doesn't need it. Avoid trimming palm trees when possible. It’s best to trim palm trees only when you notice a buildup of dead fronds. That said, leave the brown fronds during the dormant season because this organic matter helps protect the tree from the cooler weather.

It’s not always easy to tell when a tree is dying, although signs like dropping branches and brittle bark can sometimes offer clues. It can also be difficult to know whether a tree is dead or dormant, especially if it’s a deciduous tree. You’ll want to wait until a growth season to get a good idea of a tree’s health. When in doubt, contact an arborist for a consultation.
